CARDv PUNCHING CONTROL Application December 5, 19.34,, Serial No, 156,185

of piano-machine heads used in punching jacquard-cards, such as are employed in the production of a predetermined weave and pattern in textile fabrics.

The primary object of this invention is to furnish a novel means whereby the'prevailing neces- 10 sity for correcting errors in punched-cards, after initial perforation, is eliminated.

To this end I provide a springy material keyconnector in the form of a clip adapted to couple together consecutive or otherwise selected keys on a keyboard-type punching machine, whereby serial or group punching, and successive ,repeats thereof, can be effected without error.

In the drawing:

Fig. I is a plan view of a piano-machine head illustrating the application thereto of two embodiments of my novel key-coupling clip.

Fig. II is a fragmentary detail, on a larger scale, taken on the plane IIII in Fig. I; and,

Fig. III is a perspective View of one form of the key-coupling clip.

Referring more in detail to the'illustrations, a conventional piano-machine head for punching jacquard-cards is comprehensively designated by the numeral l; the same having suitable apertures 2 whereby it is attachable to the plunger of an appropriate punching mechanism; while 3-l8, inclusive, indicate the usual keys that control the card punching plungers l9-34, respectively.

In accordance with this invention, and in order to provide a simple and effective means whereby any selected, or desired group of the keys 3-!8 may be coupled for simultaneous or repeat operation, I have provided the key-coupler, comprehensively designated 35. This key-coupler 35 is preferably made of springy sheet metal to provide a rectangular body portion 36, having the upper part suitably-shaped to provide a key-top engaging or auxiliary-head 31, and with opposing end headings 38 adapted to snugly coact with the stems s of consecutive or selected keys. In Fig. I there are shown two embodiments of the invention, the one, 35, engaging the stems s of consecutive keys I and B for example, and the v other 35, similarly engaging a group of keys Il-M, inclusive. The clip 35 or 35 is provided with a key stem gripping projection 39 conveniently stamped out of the body portion 36, said projection being so shaped relative to the confronting end beading 38 as to firmly clamp the clip to the enclosed key stem s, so that both keys I, 8 can be simultaneously depressed without inconvenience to the operator.

The clip 35 is also provided with a stem gripping projection 39' for similar coaction with one 5 of the stems s of the key II, for instance, while it may be lightened by a cut-out 40 if desired; but it will be readily understood that any number of such cut-outs may be made, the same depending upon the number of keys it is desired 10 that the clip 35' should connect together for simultaneous and repeat operation.

From the foregoing it will be readily understood that by this invention the entire set of keys 3-I8 shown may be grouped together in multiple series 15 of consecutive two keys, three keys, etc; or broken consecutive series of two and three keys each, or four and three keys alternately; and otherwise as desired or required. Furthermore, by the use of the improved clips 35, 35 the cutting of jac- 20 quard cards is greatly simplified; and without the necessity for subsequent correction.

Still further, it will be apparent that among the many advantages inhering in this invention are, that the clips 35 may be easily made to depress 5 any given number of keys, while the punches 19-34 not required could be removed or put out of action; secondly there is provided a novel head adapted for the collective selection and depression of any group of keys desired by the 30 operator; and a simple means whereby the selected group of keys can be secured together for simultaneous repeat card group-punchings.

Having thus described my invention, I claim:

1. A coupler clip for the simultaneous opera- 35 tion of selected key controlled card-punching plungers embodying a main portion with a section adapted to engage the key heads, and opposing grippage portions for clamping coaction with the key controls. 40

2. A coupler clip for the simultaneous operation of selected key-controlled jacquard cardpunching plungers embodying a main portion with an upper section adapted to seat upon the selected key-control heads, and opposing end 45 grippage portions for clamping. coaction with the key control stems.

3. A coupler clip for the simultaneous operation of selected key-controlled jacquard cardpunching plungers embodying a main portion 50 with an upper section adapted to seat upon the selected key-control heads, opposedly turned end headings for coaction with the selected keycontrol stems, and an opposing projection confronting one of said end headings whereby the 55 clip is firmly clamped to one of the selected key control stems.

4. A coupler clip for the simultaneous operation of selected key-controlled jacquard cardpunching plungers fashioned from springy sheet material to provide a somewhat rectangular main portion with an upper turned over section shaped to seat upon the selected key-control heads, inwardly curved opposed end beadings for coaction with the selected terminal key-control stems, and an opposing curved-projection outset from the main portion to confront one of the end beadings whereby the clip is firmly clamped to one of the selected key-control stems.

5. A coupler clip for the simultaneous operation of selected key-controlled jacquard cardpunching plungers fashioned from springy sheet material to provide a somewhat rectangular main portion with an upper turned over section shaped to seat upon the selected key-control heads, inwardly curved opposed end headings for coaction with the selected terminal key-control stems, and an opposing curved-projection outset from the main portion to confront one of the end headings whereby the clip is firmly clamped to one of the selected key-control stems, said clip being apertured for lightening purposes. 10

6. In a device for the simultaneous operation A of selected key-controlled jacquard-punching plungers, a springy sheet metal coupler clip for engagement over the heads of a number of the plungers, said clip being adapted to removably l8 grip one of the plunger stems, whereby the others are left free for independent action.
